Features

Low input voltage control

Output voltage will be lowered when input voltage drops.

Input/output transient protection. When a transient effect detected either on input or output, the battery as well as the consumer will be temporarily disconnected as long as error is tripped. This time is measured typically in microseconds unless there is a constant interference or any other perturbation.

Soft start

Output short-circuit protection

Output overload protection. Current limited at 80 or 100 Amps depending on type

Working Theory

Rather than just constant current flowing into your cell, this adjustable PWM controls current and the resulting heat that can sometimes be an issue, by pulsing off and on rapidly. Pulse Width Modulation, also referred to as PWM is a method of transmitting information on a series of pulses. 12V 80 Amper PWM is a modulation technique for forming variable width pulses to represent the amplitude of an analog wave or signal. Voltage adjustment allows you to efficiently control the volume of hydrogen production.

The PWM is rated @ 80 up to 100 amps on 12v voltage. never load the unit with any electronic consumer (HHO cell, motor, etc.) drawing more than 95-100 amps constantly. always wire up a 100 amp fuse inline with the positive input wire. Warranty voids if fuse not applied. No surge function over the maximum amps.

Pulse Width Modulators are essential component of any water4gas system. PWM's are extremely effective in reducing heat and controlling amperage. We strongly discourage anyone installing a HHO conversion kit directly to the battery without PWM. Pulse Width Modulation, also referred to as PWM is a method of transmitting information on a series of pulses.12V 80 Amper3 PWM is a modulation technique for forming variable width pulses to represent the amplitude of an analog wave or signal. Voltage adjustment allows you to control the volume of hydrogen production. Although you can save some bucks on cheap pulse width modulator kits, a top-notch 12V 80 Amper PWM pays for itself in the long run.

Voltage adjustment

You might need to set the volume of hydrogen production with the PWM unit's potentiometer.

While adjusting the pot check the hydrogen production in the tank.

The more fresh bubbles come up to the top of the hydrogen generator the stronger the hydrogen generation is.

Right end means maximum HHO production.

Start to turn the pot slowly clockwise (right) and see the bubbling.

Wait for 30 seconds after each quarter turn, the process is delayed.

The process is easy to follow, however it takes time to understand. The optimal hydrogen production depends on several factors affecting the fuel consumption as well. You need to establish a fully active hydrogen production without extreme heat generation would lead to undesired loss in hydrogen performance. This PWM was designed with External Potentiometer and Screw Terminal Blocks in order to ensure variable position for the potentiometers mounted either in the compartment or the engine bay. Extension wiring harness not included. Recommended: American Wire Gauge - AWG 23 or lower.

it handles so much current

I like the fact that it handles so much current and I could probably even add more amps to my cell, to make hydrogen production even more powerful where current handling goes but one downside with this particular PWM unit is that the operating frequency too low. At higher frequency the amount of HHO could be even more.

units are great and relatively quiet

I purchased these pwms to go with my (removed) dry cell. They came with one fan. However, it is quiet and did cool the hardware efficiently. The units are great and relatively quiet! For the price, you cant beat this deal. They arrived in 3 days and were packaged very neatly. Taking them out of the box, they were sturdy and did not feel cheap.

Awesome little high amp controller

Awesome little high amp controller. Comes with a great little case and dial allows you to trim the current steadily and firmly. The only negative is the terminal size should be bigger to accommodate at least 4GA wire since it's rated at 100 amps.

worked fine out of the package

This pwm controller has a very nice housing and is well made. Mine worked fine out of the package. Other similar hho controllers we have tried from other vendors have a higher base PWM frequency are less efficient in hydrogen production. This product worth every single penny!

fan stopped to work after a month

fan stopped to work after a month of duty they replaced the whole pwm free but i'm not confident its gonna work longer than the 2 year warranty period, switching time square wave seems adequate but i'm still sitting on the fence i'm satisfied or dissatisfied.

in a nutshell, i ordered it assuming i got an adjustable pwm that makes me enable to adjust both Hz and amps. this unit work like a potentiometer, having a potentiometer and its preset to a fix frequency. return was easy but folks didn't seem to be keen on refunding my money. still it is refunded. as magnum pwm that features adjustable frequency is overpriced i will find this unit elsewhere.

It's a good pwm

It's a good pwm. The only downside to this unit is that the board is encased in fiberglass resin, which in itself is a good thing so it can withstand hard conditions, but the potentiometer is encased in the resin as well, making it permanently stationary, so it cannot be relocated to a panel. Overall, it's a good solid unit that runs cool. If I need a stationary 100 amp pwm again, this would be what I would choose.

Magnum Electronic Fuel Injection Enhancer was developed to modify the Oxygen Sensor signal when engine is converted to HHO. EFIE adjuster is a mist after installing a water4gas system. In this case more fuel needs to be processed to achieve ultimate MPG increase. After we deliver HHO gas into the engine, the oxygen sensor reports a change in the consistency of the exhaust gas to the Electronic Control Unit, and accordingly the ECU will compensate the missing fuel by enriching the mixture. That’s where EFIE adjuster comes to play.

Wideband EFIE O2 sensor adjuster fools 5 and 6-wire O2 sensors' signal. It tricks the ECU thinking the mix is rich, then the ECU will deliver less fuel for a leaner mix thus minimal consumption is warranted on HHO hybrid vehicles. While you are injecting HHO gas into the engine you need to lean out the air/fuel mixture if you really want to save gas.

Magnum adjustable Titania EFIE oxygen sensor adjuster wires inline between the oxygen sensor and the ECU. The EFIE Adjuster maxes out the Air Fuel Ratio by mimicking fuel rich status. While you are delivering hydrogen gas into the chambers, you need to lean out the air/fuel mixture if you are after real gas savings, otherwise the engine will run on an air / fuel blend of HHO that contains too much standard fuel, ruining the engine power and spoiling MPG enhancement.

12V 80 Amper

The PWM is rated @ 80 amps on 12V voltage. Never load the unit with any electronic consumer (HHO cell, motor, etc.) Drawing more than 75-80 amps constantly . Always wire up an 80 A fuse inline with the positive input thread. Warranty voids if fuse not applied. No surge function over 80 amps.
